Figure 1. Experimental timeline for acute mouse treadmill exercise.

Figure 1

Circadian reporter (PER2::LUC) mice completed a moderate‐intensity bout of forced treadmill exercise (60 min) in the middle or end of the resting phase (ZT5 or ZT11) and in the middle of the active phase (ZT17). Timing of exercise is defined as zeitgeber time (ZT), which represents time based on the period of a zeitgeber (time cue), in this case 12 h light:12 h dark. The grey dotted line represents the relative expression of Bmal1 mRNA over time. [Color figure can be viewed at wileyonlinelibrary.com]
